The Lynchpin in Square

First they launched this. And a hot dog stall owner in lower Manhattan could process his payments using a card reader and an app.

Well so many such small business owners liked this product that soon Square was processing  $4 billion in payments.

Now they have launched this. Can you hear the creaking sigh from the cash register? And how simple mobile apps can take over complex payment software systems at checkpoint?
